Dynegy

What Dynegy does

Dynegy is a retail electricity supplier operating as a wholly-owned subsidiary of Vistra Corp (NYSE: VST), headquartered in Irving, Texas. Founded in 1984 and legally organized as Dynegy Energy Services Mid-Atlantic, LLC, the company supplies electricity to residential, small business, commercial and industrial, and municipal aggregation customers in deregulated markets across Illinois, Ohio, Pennsylvania, and Massachusetts. Core products include Dynegy Home Energy Solutions (residential fixed/variable rate plans), Dynegy Business Energy Plans (commercial supply with rebate-funded efficiency upgrades), Dynegy Municipal Aggregation (community-negotiated rates for cities, townships, and counties), the Dynegy Dashboard (business energy management portal with weather-normalized usage analytics), and the Dynegy Cash Rewards program (5% annual cash back). The company also operates a sister brand, Homefield Energy, in Illinois.

Dynegy distributes through three primary channels: direct digital and phone enrollment, municipal aggregation programs where communities collectively negotiate supply rates, and an Aggregator/Broker/Consultant (ABC) channel serving commercial and municipal buyers. Revenue is generated via subscription/recurring electricity supply contracts billed monthly, with rates ranging from approximately 7.5¢ to 15¢ per kWh depending on geography, term length, and renewable content. The company supports renewable energy procurement through RECs and community solar subscriptions, and has secured high-visibility enterprise contracts including Willis Tower, McCormick Place, Fifth Third Bank, and OSF HealthCare.

The company has been recognized repeatedly for channel excellence, winning the ERCG Triple Crown (overall excellence, price competitiveness, ease of doing business) in 2020, 2022, and 2023. Dynegy is not publicly traded standalone — its former NYSE listing under DYN was delisted upon Vistra's April 2018 merger completion. Today it operates within Vistra's retail platform, which collectively serves approximately 5 million customers; the source data does not disclose Dynegy's standalone revenue, headcount by function, or R&D spend.
